        <h6>Runtime Information</h6>
        <p>Each time the device restarts, it will obtain a Csq value which is used to evaluate the strength of the 4G network signal. Generally, a value above 20 indicates good reception, while below 10 may indicate poor reception.</p>
        <p>Csq Min and Csq Max are stored as minimum and maximum values in the cloud.</p>
        <p>Other status values are periodically reported by the MODULE_META module, so this module must be enabled to access these data.</p>
        <p>Iccid: The ICCID number of the SIM card on the device; Imei: The IMEI number of the 4G module, usually printed on the surface of the 4G module; Ip, Mask, Gateway, Dns1, Dns2, Ipv6: Network configuration obtained by the 4G module from the operator's base station.</p>
